I had the same problem for several months. The ONT outside was replaced, the techs did work on the pole outside, I replaced the router twice, rewired my system with cat 6 cable, reset the router countless time and had five different tech visits. Nothing worked. The connection kept failing. Hours on the phone with tech support and the problem continued. Countless tech support chats with no solution.
I tested the router for a week and it continually failed. The failure would last 3 to 5 seconds and would happen 100 times in 30 minutes.
I finally replaced the Verizon router with an Asus router and this solved the problem. The Verizon router evidently has a fundamental design defect. I put the Verizon router behind the Asus router and the Verizon router would fail but the Asus router did not.
I have now had almost one month without incident. No router reboots, no dropped signals.
Bottom line is replace the Verizon router with another high-quality manufacturer's router.
There have been posts on this issue since 2015. Verizon must know their router has a design oroblem.
